The Syscom Products A3000 Internal Expansion mini-podule was badged and sold by several companies including Focus IT and Oak. There was a range of 3 internal expansions which replicated the I/O ports on the BBC Micro. The 3 mini-podules are:

The User port uses an R6522AP Peripheral Interface Adapter. The Analogue port uses an NEC D7002C Analog/Digital converter.

Options A and B are pictured above.
 
I have no documentation for this minipodule.
